我正在做我的硕士论文，我在配置交叉编译器时遇到问题。我读过很多文章，常见问题解答，教程等，但我仍然认为我错过了一些东西，可能非常愚蠢和基础，但没有这些，我不能清楚地看到一切，而且我也不会使所有工作...所以请随时解释我的一切。让我们来解决这个问题。安装mips交叉编译器的问题
我正在使用SoClib设计具有许多MIPS和许多RAM的NoC，并且我想在每个RAM中加载不同的应用程序，以使每个MIPS只从一个RAM读取。我设法用非常简单的应用程序来做到这一点（比如hello word with interrupts ...），所以现在我试图实现一个JPEG解码器，以更强烈的方式使用MIPS。问题是我使用的交叉编译器找不到基本的stdio函数，所以无法编译mips的应用程序。所以基本上我没有设法安装一个完整的交叉编译器。
1）Let's开始与SoClib安装交叉编译： 这里有导向从来就跟着来安装它：http://www.soclib.fr/trac/dev/wiki/CrossCompiler 现在从什么从来就读这不是一个完整的交叉编译器。我只安装了第一阶段的gcc，可以为mips生成elf代码，但不能使用任何C函数。用那个，我应该编译一个C库来创建一个新的交叉编译器。所以这是正常的，它不工作，虽然这并不回答这个问题：为什么“Hello world”工作，如果它使用printf并包括stdio.h？答案应该是我已经看到SoClib的头文件stdio.h中实现了很少的功能（printf在那里），所以我不能在该编译器中使用标准的C库。 2）因为这个，我决定安装一个完整的交叉编译器，并且我已经阅读了很多指南，我只会发布我在练习中使用的两个： http://www.cse.iitb.ac.in/grc/gcc-workshop-11/downloads/slides/gccw11-config-build.pdf（从第108页开始）交叉编译问题） 它使用EGLIBC。唯一的区别是我用作目标“米勒精灵”。如果我理解正确，这种方法需要3阶段交叉编译器，因为eglibc不能用第一阶段交叉编译器完全编译。现在的问题是，我无法用第一阶段交叉编译器安装eglibc（它在第122页失败）。我附上了日志。我认为问题开始于它说：“mipsel-elf-gcc：错误：无法识别的选项'-V'”和“mipsel-elf-gcc：致命错误：没有输入文件编译终止”。似乎我有一些编译器的问题，并完成一个不支持的平台......但它应该工作，因为我已经复制eglibc/ports目录像指南所说...
3）我试过另一个指南，使用newlib而不是eglibc： http://www(dot)cygwin(dot)com/ml/crossgcc/2005-08/msg00114/l-cross-ltr.pdf 本指南仅创建2阶段交叉编译器。我认为这是因为newlib可以用第一阶段编译器完全编译......我是对的吗？无论如何，我遇到同样的问题。我无法编译newlib，并且出现类似的错误（附加日志）。
所以这是我的问题，在这里我提出了一些疑问，我试图解决它。
4）问题可能是目标= mipsel-elf吗？我从gnu文档中知道，配置gnu的名字应该是：cpu-manufacturer-os（或者cpu-manufacturer-kernel-os），但我读过mipsel-elf被接受。小精灵应该是因为我不想在我的NoC平台上加载操作系统，这里有第二个疑问......
5）问题是操作系统的问题吗？这些指南使用Linux内核头文件...也许有一个mipsel-elf目标我不应该配置binutils -with-sysroot？但听起来很奇怪......应该改变什么？
6）又一个可能是愚蠢的问题。 stdio和一般的C函数，不需要一个操作系统？因为所有这些问题都让我对基础知识产生怀疑......所以我应该能够用mipsel-elf交叉编译器运行JPEG解码C应用程序吧？
每一个考虑，建议和帮助将不胜感激。如果你有一些关于这些论点的文件，请让我知道，我想学习，并在这个领域变得更加自信。 感谢
